Title: Method for operating blast furnace
Inventor: YAMAGUCHI KAZUYOSHI
IPC: C21B5/00
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To improve the combustibility of waste plastics and to assure air permeability by installing a lance for blowing the waste plastic through a tuyere and blowing the waste plastic of a specific grain directly into a raceway. SOLUTION: Pulverized coal is blown from a lance 3 inserted from the side wall part of a blast branch pipe 2 mounted at the tuyere 1 of the tuyere section of a blast furnace and the waste plastic of <=10mm grain size is blown from the lance 4 for blowing the waste plastic installed through the tuyere 1. The pulverized coal is blown into the blast branch pipe 2 and the waste plastic is directly blown into a raceway 7. Either or both of the blast temp. and oxygen enriching rate are adjusted according to the blowing rate of the waste plastic to be blown directly into the raceway and the grain size of blowing. If the waste plastic is directly blown into the raceway 7, the waste plastic is rapidly heated in the high-temp. field of about >=2000 deg.C in the raceway 7 and is made into the finer grains. Consequently, the combustibility is improved.

Title: Plastic package for semiconductor
Inventor: NAKAMURA HIROTAKA
IPC: H01L23/50
Filed: 1989-12-04
Abstract: PURPOSE:To reduce lead inductance of a multipin plastic package and to realize high-speed LSI performance without causing erroneous function by pasting a board having a wiring layer to at least on one side of a lead frame and then, connecting electrically the lead frame to the wiring layer in the board. CONSTITUTION:In a plastic package which uses a lead frame 3 and a mold resin 4, each board 5 having a wiring layer is pasted at least on one side of the lead frame 3 and the lead frame 3 is connected electrically to the wiring layer of the board 5. In this way, the lead frame 3 and a wire 2 are in existence between a semiconductor chip 1 and each outer lead and yet, as each board that is equipped with patterns of metallic conductors in parallel is connected to the lead frame 3, inductance in the lead frame becomes exceedingly low. Further, with the speeding-up of an LSI, although the change rate of output becomes rapid, the plastic package which takes out the performance of the high-speed LSI without giving rise to erroneous function is obtained by decreasing lead inductance.

Title: Production of water absorbable composite
Inventor: OHIRA KATSUJI
IPC: D06M101/16
Filed: 1987-12-16
Abstract: PURPOSE: To produce an excellent water-absorbing complex having high strength by fusing together a water-soluble resin powder on the outer surface of a low-melting layer of a tape-like laminate or the like comprising high-melting and low-melting synthetic resin layers and then by subjecting the water-soluble resin powder to crosslinking treatment with a foaming crosslinking agent. CONSTITUTION: This water-absorbing complex is produced by the following steps: (1) the formation of a tape-like laminate (or its split fiber or conjugated fiber) where the laminate comprises a high-melting synthetic resin layer 1 and a low-melting synthetic resin layer 2 and the low-melting layer is disclosed from the surface; (2) heating the laminate up to the vicinity of the melting point of the low-melting resin and fusing together a water-soluble resin (e.g. polyacrylic acid or its copolymer or the like) on the outer surface of the low-melting layer discolored from the surface; (3) making the water-soluble resin contact with a foaming aqueous solution comprising a crosslinking agent (e.g. sorbitol polyglycidyl ether or the like) and a foaming agent such as a surfactant and applying crosslinking treatment.  The high-melting synthetic resin is e.g. a crystalline polypropylene or the like. The low-melting synthetic resin is e.g. an unsaturated carboxylic acid-grafted modified polyolefin or the like. The laminate may have three layers e.g. consisting of the layer 2, the layer 1 and the layer 2 as the tape-like laminate.

Title: Facsimile device
Inventor: YAMAGUCHI YOSHIBUMI
IPC: B65H3/04
Filed: 1990-11-20
Abstract: PURPOSE:To improve reliability of document carrying at the time of sending by comprising an auxiliary roller, which repeats to project and to be buried, a document presser plate, a paper feeding roller, a paper feeding pad, and a paper feeding belt, which is stretched between the paper feeding roller and the auxiliary roller. CONSTITUTION:A paper feeding belt 5 and an auxiliary roller 3 connected to the paper feeding belt 5 are rotated by the rotation of a paper feeding roller 4, and the document is supplied one by one from the lower side by the paper feeding belt 5 and a paper feeding pad 6. Since the contact surface of the paper feeding belt 5 with the document is not a roller but a belt, friction with the document is large, and the carrying force is large to carry the document securely. A document flux is supplied one by one in order, but since an auxiliary roller 3 of the paper feeding belt 5 is formed into non-round form, the paper feeding belt 5 repeats to project from the document carrying surface of a document supplying tray 1 and to be buried in the document carrying surface at a part near the auxiliary roller 3. The contact time of the paper carrying belt 5 with the document is thereby adjusted to prevent overlapped-carrying to be generated by prolonging the contact time at the time of separation.

Title: Treatment of metal surface
Inventor: YONEMOTO TAKAO
IPC: B05D3/10
Filed: 1994-12-20
Abstract: PURPOSE: To form a film excellent in corrosion resistance to improve the life of lining in powder coating of polyethylene by immersing a metal surface in aqueous solution of phosphate to form a chemical film on the metal surface before applying a chromate surface treating agent. CONSTITUTION: In a method of treating a surface in corrosion resistant polyethylene powder coating to steel, particularly zinc plated steel such as pipes used for piping of various devices, first after the steel is immersed in aqueous solution of phosphate to form a chemical film on the metal surface, a chromate surface treating agent is applied. That is, after a chemical conversion film is formed by phosphate zinc treatment, a chromate film whose surface energy is close to that of the chemical film is formed, thereby a flaw in a crystal of phosphate is filled to sharply improve corrosion resistance of a surface treated layer. Thus, adhesive force to powder coating of polyethylene is improved. Therefore, by a relatively simple method, corrosion resistance is improved to form a polyethylene lined coating film of high reliability.

Title: Game ball discharge device
Inventor: NIIYAMA KICHIHEI
IPC: A63F7/02
Filed: 1992-11-27
Abstract: PURPOSE:To provide a game ball discharge device capable of correctly discharging a designated number of game balls even if a sprocket is rotated by using a game ball which naturally falls along a guide path. CONSTITUTION:Sprockets 41, 42 are rotated by game balls which flow down along guide paths 30, 31 for guiding the game balls which flow in a casing. The rotation of the sprockets 41, 42 is transmitted to an input shaft 71 of an electromagnetic clutch through a first gear 51 and a second gear 52. When an electric current is applied to the electromagnetic clutch, the input shaft 71 becomes free and rotates, following the rotation of the sprockets. When a designated number of game balls are discharged and the electromagnetic clutch is put in the non-current carrying state, the input shaft 71 is braked by an output shaft fixed to the case of the electromagnetic clutch. The braking is directly transmitted to the sprockets through the gears 51, 52, so that a designated number of game balls can be discharged correctly.
